[A forgotten chapter in the prehistory of psychoanalysis in Cologne. The emigration of Hans Erich Haas (1896-1990)].

Haas was the first medical doctor from the Rhineland who was trained at the Berlin Psychoanalytic Institute and established himself as a "specialist for psychoanalysis" in Cologne. For nearly ten years he had a flourishing practice there with a particular interest in the treatment of schizophrenia. He was Jewish and in 1936 he emigrated to England where he was the first and for a long time only psychoanalyst in Birmingham. He specialised in treating patients with personality disorders and psychosomatic diseases and was increasingly consulted as a forensic expert. As a result of his association with a hospital and with the university, he was instrumental in the foundation of the West Midlands Institute for Psychotherapy. At the time of his death in 1990, the psychoanalytic study group of Cologne lacked any knowledge of his life or work.
